Tower or mast construction



oct. 16, 1945i Zinesses H. COHEN TOWER OR MAST CONSTRUCTION Filed April4', 1944 INVENToR. l Harold Cohen Patented Oct. 16, 1945 hisinventionlrelates to fabrication of towers,

masts andl analogous structures.

VW{Ihe principal object Yof the invention ,is the provision of meanswhereby component parts may be transported fromshop to eldand be.

quickly,A easily vand effectually connected with each other to formstructures of the character mentioned for use where wanted. Also, toenable such structures to be dismantled so that the component parts maybe removed and stored in comparatively small space when not in use.

Other objects of the invention will appear when the followingspecification is read in conjunction with the accompanying drawing, inWhich- Fig. 1 is a side elevational view of a portion of a tower or mastembodying the features of the invention, some parts being broken awayand shown partly in section and parts being juxtaposed to illustratecertain features of the fabrication.

Fig. '7 is a sectional view taken on the line I--l of Fig. 6.

Fig. 8 shows a further modification.

In the drawing, by way of example, there is shown components of a toweror mast. The structure may be of any height and of any forma.- tion incross section, the same being triangular in the present instance. Thetower or mast is fabricated in accordance with the invention by meansoi' devices and structura1 elements prefabricated in a shop and usedwith certain other elements which are provided to be integrated withsuch prefabrications to form the tower or mast.

Referring now more particularly to Fig. 5vof the drawing, it will beapparent the tower or mast includes three supports or legs II! eachconsisting of sections II arranged end to end. These sections II andtherefore the legs are rigidly connected to each other by means of thepresent invention as follows.

Tubular members I2 of similar size and shape are ridigly connected toeach other by tie bars S" PATENT EGF-,FICE 2,387,120?? 1 .Jf i" Y TOWER0R MAs'r coNsTnUorI'N-f l w l" Vnamid-cohen,ltiiahtiiffiv.u;'e7v f.Application Aprilkfi, 1944*; seria1 Ndszaiss I Y2 claims. (crise-26) A Ywww |13. 'lilach member I2 is round in cross-section and each tie bar isinthe form of'a channel iron of .suitable-length. The bars I3`'are r`secured to the members AHI2 as bylwelding `to 'rigidly hold the membersin spaced vvrelation-dto eachifother, the parts forming a'. triangularunit Illprefabricatedin the shop, the sameY nbeing f. best 'seen' inFig. 2. A -suitable number of these units I4 are used according to theheight of the 4tower or mast desired.

Each of the leg sections II is round in crosssection to fit into atubular member I2 and said section II may be of any preferred lengthalthough all sections Il are advantageously of the same length. Each legsection' I I has collars I5 xedly secured thereto near the opposite endsrespectively. Of course, each of the lowermost and uppermost legsections require a single collar. Each collar I5 has a radially disposedapertured lug I6. The lug I6 of the lower collar of each leg section IIhas connected therewith a rigid link or connector I1 by means of a pivotbolt or the like I8, so that the link may have pivotal movement. All ofthe links are applied in the shop to remain attached to the respectiveleg sections. Each link I1 is made from a single metal strip bent uponitself into U-shape to provide equal members I9 joined by a bight 20.The members I9 have registering holes 2| in the opposite ends thereofand those at one end of the link remote from the bight 20 to receive thebolt I8. A ller block 22 is secured between the members I9 and a hole 23extends through the members I9 and the block 22 to receive one end of aguy line or the like 24 when the tower or mast is erected.

In erecting a tower or mast, a group of leg sections II, three innumber, have a unit I4 applied thereto in which the upper ends of thesections II are received in the tubular members I2 respectively, withthe collars I5 abutting the lower' ends of the members I2. A secondgroup of leg sections II are inserted into the aforesaid members I2,respectively, with the lower collars I5 thereof abutting the upper endsof the members I2. The links I'I are then swung into engagement with thelugs I6 of the lower leg sections II, bringing the bight 2i) of eachlink into engagement with the related lug I6. A bolt 25 or the like isremovably inserted in the registering holes 2l in members I9 near thebight 2! and the hole in the lug I ii. In this manner one group of legsections II is rigidly connected with another group in which the legsections II are arranged end to end, the collars I5 abutting the Il byvirtue of the holes 23, as shown in Fig. 5.

In Figs. 6 and 7, a modification is shown in which a lug 30 of U-shapeis used in lieu of the solid lug- L'nlrlstheA lug 30 oneeach-iuppercollar I5 hasfatubular nllerguiece .f3ivwe1dediineplace to receive aplain bolt 32 which engages the bight 20 of the link I1.
